WHEEL.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application led December 11, `1911. Serial No. 665,067.

to improvements in ment of the wheel is such that the hub,

spokes and rim are composed of parts which after having been assembledtogether are filled or cast out with an artificial-wood mass, so as toform one single body.

My invention relates also to a metallic hub comprising several pieces,said metallic hub receiving the inner ends of the spokes and holding thesame by means of said artificial wood-mass.

Furthermore, my invention relates to 4a rim formed of a metallic ringadapted to take up the outer ends of the spokes and to receive theartificial-wood mass intended for holding the parts together, thearrangement being preferably such that an elastic layer or lining issituated between the outer surface ofthe articial-wood mass and theiron-tire of the wheel.

By using the metallic hub and spoke-ring which according to my inventionhave only to be filled out with artificial-wood mass great advantagesare obtained consisting for example in great simplicity of constructionand great facility in fitting up or erecting the wheel. Furthermore, nospecial forms are necessary for filling or casting out the hub and thespoke-ring made according to my invention. y

I am aware that wheels formed of articial-wood mass and metallicarmatures are already known, but not with the special arrangement andcombination of parts forming the object of my invention.

In the accompanying drawing forming a part of this specification, and inwhich similar letters of reference relate to corresponding partsthroughout the several views, Figure 1 is a front-view of a wheelconstructed according to my invention, Fig. 2 is a vertical section ofsame, Fig. 3 a sideview of the hub, Fig. 4 a longitudinal seclisinserted the wheel-bush la.

.artificial-wood mass f1 being provided with ltion of same, Fig. 5 asection of the rim on the line A-B of Fig. 1.

Referring now to the drawings the hub of the wheel is composed of ahollow body a which is formed of two parts provided with median fiangesbent inwardly at a right angle and abutting together so as to keep bothhub-pieces in place. Further the hub a possesses openings d formed inboth of said hub-parts, intended to receive the corresponding inner endsof the spokes of the wheel. Moreover, the outer edges of the openings dcarry iiaps b1 being bent inwardly to a right angle. Said flaps b1 forman abutment against which rest the corresponding parts of the spokes andat the same time serve to afford a firm connection between the hub a andthe artificial-wood mass m. Into the hub a The spokes e fastened attheir inner ends in said openings Z are made of wood or, if desired, ofmetallic tubes and pass at their outer ends through a spoke-ring fsurrounded by an said spoke-ring f bends engaging into saidartificial-wood mass f1. In wheels of `strong construction or heavycharacter the wooden spokes are provided on both sides with areinforcement formed of a metallic strip or rod tresting against thecorresponding side of the spoke, said strips or rods engaging with theirsuit-ably bent ends into the artificial-wood masses m and f1, whereby aconnection of great strength and resistance between the spokes c andsaid artificial-wood masses contained in the hub and the wheelrim isobtained.

In wheels of light character rods c passing through correspondingopenings of the spokes are sufficient for forming the joint. As alreadymentioned, the hub a, the spokes e and the spoke-ring f are readilyconnected and easily filled with artificial-wood mass m and f1, so thata very efficient connection is obtained in this way. The outer surfaceof the artificial-wood mass f1 of the rim is preferably provided with anelastic layer or lining Z intended to take up or annihilate thevibrations or jerks of the wheel and to protect the iron-tire g of thewheel against the corrosive action of the artiicial-wood mass whichcontains magnesium chlorid. Preferably the hub a is also formed with aninner said openings 0l being reinforcing ring 7L the one extremity ofsaid ring ZL being embedded in the artificial-wood mass m. Of course,the parts Z) oit' the hub a may also engage into each other instead ofabutting together.

Having thus described my invention, what I claim and desire to secure byLetters Patent of the United States is 1. In a wheel for cars and othervehicles, the combination lwith spokes and a hub to which the inner endsof said spokes are secured, of a spoke-ring f receiving the outer endsof said spokes, an artificial-wood mass flfcast around said outer endsof the spokes and said spoke-ring f, the latter having inwardly directedbends engaging in said artiiicial-wood mass, and a tire encircling saidartificial-wood mass.

2. In a wheel for cars and other vehicles, the combination with spokesand a rim, of a hub a comprising two parts, said hub a being providedwith openings cZ formed in both of said hub-parts, said openingsreceiving the inner ends of the spokes, flanges Z) bent inwardly betweensaid openings, said flanges abutting together so as to keep bothhubpieces to a predetermined distance from one another, iiaps b1 carriedby the outer edges of said openings cZ, said iiaps b1 forming abutmentsbetween which are clamped the inner ends of the spokes, and anartificialwood mass m filling out said two hub-parts, saidartificial-wood mass surrounding said iiaps b1 so as to augment thestrength of the connection, substantially as described.

8. In a wheel for cars and other vehicles, the combination with spokes,of a hub a con sisting of two hollow pieces abutting together andprovided with openings Z receiving the inner ends of said spokes, anartiicial-wood mass m filling out said two hollow hub-pieces, aspoke-ring f receiving the outer ends of the spokes, a tire g encirclingsaid spoke ring and an artificial-wood mass f1 illing the intervalbetween said spoke-ring j and said tire g, substantially as described.

4. In a wheel for cars and other vehicles, the combination with spokes,of a hub a consisting of two hollowpieces abutting together and providedwith openings cZ receiving the inner ends of said spokes, anartificial-wood mass m filling out said two hollow hub-pieces, aspoke-ring j receiving the outer ends of the spokes, an artificial-woodmass 1 cast around said spoke-ring f, the latter having bends engaging`into said articialwood mass f1, an elastic lining Z surrounding saidartificial-wood mass f1, and a tire g encircling said artiiicial-woodmass f, substantially as described.

5. In a wheel for cars and other vehicles, the combination of a hub aconsisting of two hollow pieces abutting together and lprovided withopenings cZ receiving the inner ends of the wheel spokes, anartiicialfwood mass m iilling out said" two hollow hubinner ends intosaid openings cZ of the hub a, a spoke-ring f receiving the outer endsof said spokes c, an artificial-wood mass f1 cast around said spoke-ringf, an elastic lining Z surrounding said artificial-wood mass f1, a `tireg encircling said artificial-wood mass f1, and two strengtheningmetallic strips t arranged upon the two outer surfacesof the woodenspokes c, said strips being provided with bends engaging into theartificial-wood mass m and f1 so as to produce a stronger and moreefficient connection, substantially as described.

6. In a wheel for cars and other vehicles, the combination of a hub@consisting of two hollow pieces abutting together and provided withopenings Z receiving the inner ends of the wheel-spokes, anartificial-wood mass m filling out said two hollow hubpieces, woodenspokes e engaging with their inner endsl into said openings Z of the huba, a spoke-ring f receiving the outer ends oi' said spokes e, anartificial-wood mass f1 cast around said spoke-ring f, an elastic liningZ surrounding said artificial-wood mass f1, two strengthening metallicstrips t Varranged upon the two outer surfaces of the wooden spokes e,and a metallic armature c passing through the inner ends of the spokes efor keeping the same better in place in said artificial-wood mass m,substantially as described.-
